ADJUSTABLE TABLE.

SPECIFICATION forming part of Letters Patent No. 533,022, dated January22, 1895.

Application filed October 1, 1894. Serial No. 524,569- (No model.)

To all whom it may concern:

Be it known that we, GEORGE SHEAR and ANDREW W. QUINLAN, citizens of theUnited States of America, residing at Joliet, in the county of Will andState of Illinois, have invented certain new and useful Improvements inAdjustable Tables, of which the following is a specification, referencebeing had therein to the accompanying drawings, and the letters ofreference thereon, forming a part of this specification, in which Figurel is a side elevation of the adjustable table as it would appearstanding on the floor ready for use. Fig. 2, is a side elevation of aportion of the table post, and a central Vertical section of a slidingcollar thereon..

Fig. 3 is a side elevation of a portion of the table post showing a faceview of its ratchet teeth. Fig. 4 is a cross sectional view of the tablepost, and a bottom plan view of one of the collars thereon. Fig. 5 is aside elevation of a portion of the table post, and a central verticalsection of a sliding collar thereon, being a reverse view of Fig. 2,showing the opposite sides of the ratchet teeth of the table post. Fig.6 is a plan view of an arm and a section of a table board attachedthereto, and showing an integral collar attached to said arm foradjustment on said table post and Fig. 7, is a cross sectional view ofthe table post.

This invention relates to certain improvements in adjustable tableswhich improvements are fully set forth and explained in the followingspecification and claim.

Referring to the drawings B represents the table post formed in crosssection as shown in Fig. 7, and having its lower end secured in a bellshaped base K by means of a set screw, and provided its entire lengthwith downwardly projecting ratchet teeth formed so that one edge of theface T is higher than its opposite edge V as shown in Figs. 3 and 5.

D is a collar adapted to slide on the table post B, and is provided onits upper end with teeth for fitting the spaces between the teeth ofanother collar 0 above and designed to rest on collar D. 7

The collar D is provided on its inner wall with a conical shaped lug Whaving its face grooved to fit the beveled face of the teeth of the postB. The teeth on the post B, and the lug W are for the purpose of givingadjustment-to the collar D anywhere along on said post to regulate theheight of the tables that through the medium of its collar 0 rests oncollar D. To regulate or adjust the collarD along on said post, lookingat Figs. 2 and 5, it is intended to grasp the collar D and move it up soits lug W is free from the ratchet tooth on which it rests, when thecollar is par tially rotated so its said lug will be in the channel Y ofthe said post, and extending alongits entire length. It may then bemoved either up or down, and then partially rotated back to its firstposition so its lugWwill rest upon the face of one of said ratchet teethand thus support said collar at such place, so that no set screw isneeded to hold said collar at any desired place. The form of the ratchettooth face and of the said lug Wprevents rotation of said collar whileit is adjusted as shown in Figs. 2 and 5.

X is an arm having a dovetail groove its entire length for receiving oneend of the table board A as shown in Figs. 1 and 6. Said arm is providedwith an integral collar C having both ends toothed to fit the teeth onthe upper end of the collar D, as said collar 0 is placed on the post Bas shown in Fig. 1. The said table board may be turned to extend in anydesired direction simply by raising collar 0 so its teeth are free fromthose of collar D, and when the table is in the position desired, may bemaintained in such position by simply letting collar 0 down so its teethwill fit the spaces between the teeth of collar D as shown.

Z is a cap fitted to the top of the post B and provided with a shelf Fadapted to hold articles, and is provided with pins G for holdingspools, and said cap is also provided with an arm or hook H upon whichto hang any article desired.

Having thus described our invention, what 5 we claim as new, and desireto secure by Letters Patent, is as follows:

In an adjustable table the combination of the post B having the seriesof downwardly projecting bevel faced ratchet teeth, and havtoo ing thelongitudinal groove Y, the base K E, and the cap having the shelf F andarm 11 for supporting said post, the collar D having all arranged tooperate substantially as and to its lug W on its inner Wall and formedto fit for the purpose set forth.

the bevel face of said ratchet teeth, and hav- GEORGE SHEAR.
